RO reverse osmosis device
RO reverse osmosis The reverse osmosis device separated from the pure water and solute-containing solution which can only be semi-permeable membrane through water. At this time, the water of the pure water side spontaneously passed a semipermeable membrane into the solution side ,and the solution side of the water increased, this phenomenon is penetration. When the liquid level rises to a certain height, the pressure on both sides of the membrane will reach equilibrium, the surface of the solution side is no longer increased .At this time, the membrane on both sides will be a pressure difference, which is called the osmotic pressure.
